[0027] like Figure 1-4 As shown, this application embodiment provides a cold compress type breast pump, including: a horn cover 1, one end of the horn cover 1 is a constricted end and the other end is a flared end, and an accommodating cavity 11 is formed inside the horn cover 1. The accommodating cavity 11 can fit and at least partially accommodate the breast without gaps, forming a closed cavity.

[0028] T-joint 5 is sleeved on the constricted end of the speaker cover 1 and forms part of the cavity wall of the sealed cavity.

[0029] The partition 6 is sleeved on one end of the horn cover 1 near the tee 5. The other edge of the horn cover 1 is bent and extended toward one end of the tee 5. The edge of the partition 6 is connected to the bent edge of the horn cover 1 to form a power cavity 14. The bent part of the horn cover 1 is provided with several through holes 12.

[0030] At least one negative pressure chamber 3 is connected to a sealed cavity, and the negative pressure chamber 3 is used to generate negative pressure in the sealed cavity.

[0031] Negative pressure pump 4 is installed inside the power chamber 14 and is connected to the negative pressure chamber 3. Negative pressure pump 4 is used to extract gas from the inside of the negative pressure chamber 3 and to exchange gas with the inside of the power chamber 14.

[0032] In this embodiment, the inner wall of the speaker cover 1 can fit against the user's breast, and when the user's breast fits against the inner wall of the speaker cover 1, the sealed cavity formed by the speaker cover 1 and the three-way connector 5 is in a sealed state.

[0033] The negative pressure pump 4 can discharge part of the gas extracted from the negative pressure chamber 3 into the power chamber 14, so as to achieve the purpose of exchanging the gas inside the power chamber 14 with the outside gas;

[0034] During operation, the inner wall of the speaker cover 1 is first made to fit against the user's breast. Then, the negative pressure pump 4 is activated. The negative pressure pump 4 extracts the gas inside the sealed cavity, creating a negative pressure inside the sealed cavity. When combined with the speaker cover 1, this creates pressure on the user's breast to squeeze out breast milk, thus achieving the effect of milk extraction. At the same time, the negative pressure pump 4 discharges the extracted gas into the power chamber 14. The gas inside the power chamber 14 is then discharged through the opening 12, promoting gas exchange.

[0035] In addition, as the working time of the breast pump increases, the temperature of the air inside the power chamber 14 gradually rises. The negative pressure pump 4 continuously exchanges gases to expel the hot air inside the power chamber 14, thereby achieving the purpose of cooling down. This can effectively alleviate the discomfort caused by the temperature rise during the breast pumping process and improve the user's comfort.

[0036] This application provides a through hole 12 on the surface of the horn cover 1. With the cooperation of the negative pressure pump 4, the inside of the breast pump is constantly exchanging gas and expelling the hot air inside to achieve the purpose of cooling. This can effectively alleviate the discomfort caused by the temperature rise during the breast pumping process and improve the user's comfort.

[0037] Optionally, the outlet end of the through hole 12 is located in the bent part, and the outlet end is aligned with the user's breast and forms a gap with the breast surface. The purpose of this arrangement is to allow the discharged air to achieve a blowing effect, which can further and effectively improve the user's comfort.

[0038] In one embodiment, the system also includes a milk collection container 2, with one end of the sleeve tee 5 of the horn cover 1 extending into the interior of the milk collection container 2 together with the tee 5.

[0039] In this embodiment, any container that can collect and store breast milk can be regarded as a milk collection container 2, such as a baby bottle, a bowl-shaped container, etc.

[0040] In this embodiment, the cross-sectional shape of the milk collection container 2 is semi-circular, and when the milk collection container 2 is assembled with the horn cover 1, it forms a hemispherical shape.

[0041] Furthermore, the surface of the milk collection container 2 is provided with a liquid outlet 21, which is used to pour out the breast milk inside the milk collection container 2.

[0042] In one embodiment, the negative pressure chamber 3 includes a first half-shell 32, a second half-shell 33, and a flexible member 34. The first half-shell 32 and the second half-shell 33 together form the negative pressure chamber 3. The flexible member 34 is located between the first half-shell 32 and the second half-shell 33. The flexible member 34 and the first half-shell 32 form a first sealing cavity, and the flexible member 34 and the second half-shell 33 form a second sealing cavity. The first sealing cavity is connected to the sealed cavity through a first flexible hose 31, and the second sealing cavity is connected to the negative pressure pump 4 through a second flexible hose 41.

[0043] In this embodiment, one side of the first half-shell 32 shares a wall with the speaker cover 1, the flexible member 34 is made of silicone or rubber, the connection between the first half-shell 32, the second half-shell 33 and the flexible member 34 is a sealed connection, and the flexible member 34 and the second half-shell 33 form part of the cavity wall of the sealed cavity.

[0044] During operation, the inner wall of the speaker cover 1 is first brought into contact with the user's breast. Then, the negative pressure pump 4 is activated, which extracts the gas from the first sealed cavity. At this time, a negative pressure is formed inside the sealed cavity, causing the flexible part 34 to deform. The volume of the second sealed cavity increases, causing a negative pressure to be generated inside the sealed cavity at the same time. Combined with the speaker cover 1, this will exert pressure on the user's breast to squeeze out breast milk, thereby achieving the effect of milk extraction. At the same time, the negative pressure pump 4 will discharge the gas extracted from the first sealed cavity into the power chamber 14. At this time, the gas inside the power chamber 14 will be discharged into the power chamber 14 through the through hole 12, promoting gas exchange.

[0045] In one embodiment, a plurality of through holes 12 are arranged in a circular array around the axis of the horn cover 1.

[0046] In this embodiment, the through holes 12 are evenly distributed on the surface of the speaker cover 1 to achieve uniform heat dissipation.

[0047] In one embodiment, the edge of the speaker cover 1 is curved and smoothly transitioned.

[0048] In this embodiment, the edge of the speaker cover 1 is curved and has a large curvature, which can effectively distribute the pressure area when the user is under pressure, thereby reducing pain.

[0049] In one embodiment, a control board 7 is provided inside the power cavity 14, and a number of buttons 8 are provided on the surface of the bent part of the horn cover 1. The buttons 8 are electrically connected to the control board 7.

[0050] In this embodiment, the control board 7 is used to receive instructions from the button 8 and send the instructions to the corresponding working component;

[0051] Button 8 includes a power on / off button, a speed setting button, a pause button, and a mode switching button. The power on / off button is used to control the breast pump to start and stop. The speed setting button includes a "+" button for increasing the speed and a "-" button for decreasing the speed. The pause button is used to control the breast pump to stop working. The breast pump of this application has a massage mode, a milk expression mode, a stimulation mode, and an automatic mode. The mode switching button is used to switch between the four modes of the breast pump.

[0052] like Figure 5-6 As shown, in one embodiment, the tee member 5 includes a body 51, which is hollow inside and has a cylindrical shape with an opening at one end.

[0053] The first connecting pipe 52 is disposed on the side wall of the main body 51 and communicates with the interior of the main body 51;

[0054] The second connecting pipe 53 is located at the other end of the main body 51 and communicates with the interior of the main body 51. The opening of the second connecting pipe 53 at the end away from the main body 51 is duckbill-shaped, and elastic deformation can occur at the opening of the second connecting pipe 53.

[0055] The main body 51, the first connecting pipe 52, and the second connecting pipe 53 are integrally formed.

[0056] In this embodiment, the open end of the main body 51 is used to connect with the horn cover 1 in the breast pump, the first connecting pipe 52 is used to connect with the negative pressure generating device in the breast pump, that is, to connect with the first sealing cavity, the second connecting pipe 53 is used to connect with the milk collection container 2, and the closed end of the horn cover 1 is provided with a notch 13 at the position corresponding to the first connecting pipe 52 to avoid the opening of the first connecting pipe 52.

[0057] The second connecting tube 53 is designed in a duckbill shape and is made of silicone. Its purpose is to prevent the breast milk in the milk collection container 2 from flowing back into the sealed cavity when negative pressure is generated in the breast pump cavity.

[0058] Specifically, when negative pressure is generated inside the breast pump cavity, the internal air pressure is lower than the external air pressure, which causes deformation at the second connecting tube 53, causing the second connecting tube 53 to close. At the same time, the closure of the second connecting tube 53 can also prevent gas leakage, increase airtightness, and improve the milk expression effect. When the negative pressure disappears, the second connecting tube 53 will open again, and the expressed breast milk will flow from the second connecting tube 53 into the milk collection container 2.

[0059] This application sets the opening of the second connecting pipe 53 of the three-way fitting 5 in the shape of a duckbill, and the main body 51, the first connecting pipe 52 and the second connecting pipe 53 are integrally formed. This not only realizes the function of a one-way valve, but also reduces the installation of one-way valves and ensures the sealing of the negative pressure chamber of the breast pump.

[0060] In one embodiment, the main body 51, the first connecting pipe 52, and the second connecting pipe 53 are made of rubber or silicone.

[0061] In this embodiment, the main body 51, the first connecting pipe 52 and the second connecting pipe 53 are made of rubber or silicone. Rubber or silicone has plasticity, which allows the main body 51, the first connecting pipe 52 and the second connecting pipe 53 to be integrally formed by injection molding.

[0062] In addition, using rubber or silicone materials can effectively avoid pain in the user's breasts due to contact.

[0063] In one embodiment, the first connecting pipe 52 is set at an angle to the outer wall of the main body 51, and the opening of the first connecting pipe 52 at the end away from the main body 51 is parallel to the opening direction of the main body 51.

[0064] In this embodiment, by setting the first connecting pipe 52 at an angle to the outer wall of the main body 51, the first connecting pipe 52 is tilted, which can prevent the liquid sucked into the main body 51 from directly entering the negative pressure pump 4 through the first pipe and causing damage to the negative pressure pump 4; at the same time, the pipe opening of the end of the first connecting pipe 52 away from the main body 51 is parallel to the opening direction of the main body 51, which is beneficial for the connection with the negative pressure pump 4.

[0065] In one embodiment, the opening end of the main body 51 is flared, and the inner wall of the main body 51 near the opening end is provided with a stepped structure or a threaded structure.

[0066] In this embodiment, the flared design facilitates fitting onto the end of the horn cover 1, and the stepped or threaded structure inside can improve the stability and sealing of the connection between the main body 51 and the horn cover 1.

[0067] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
